Thermwood C40, Siemens 611U/E. Oak

Post by EastWood »

Just starting the retrofit, looking to learn about these Siemens drives and if they are good enough to keep or upgrade to Yaskawa and be done with it.

The machine ran where I bought it, and after the move the computer is way too finicky to put it to work. Wont boot, crash etc. I know the servos run fine although the do make quite a bit of noise sitting idle. Thoughts?

I am no expert in this field, but I am willing to put the time and work in to figure it out. Looking for direction on where to find the info.

Is this enough info to figure the Pinout for the drives?
I have the Siemens book for series 6SN11.
